That's the we we used to dive before there were BCs. Of course it was typically pretty shallow compared to now. No depth guage or air guage, etc. All we had was our octo, tank and a reserve valve. You just dove till you couldn't suck air, pulled the reserve valve and surfaced.
Of course those dives were pretty shallow, so if you want to go back to the "good ole days" it's probably ok as long as your pretty shallow.
Now with deeper dives and having the luxury of perfect trim and bouyancy, I'm never going back unless I'm free diving.
Dive well!
